DESCRIPTION
21
RYEL
O
Receive Yellow Alarm.
Transitions high when yellow alarm detected, goes
low when alarm clears.
22
RLINK
O
Receive Link Data.
Updated with extracted FDL data one RCLK before start
of odd frames (193E) and held until next update. Updated with extracted S-bit
data one RCLK before start of even frames (193S) and held until next update.
23
RLCLK
O
Receive Link Clock.
4 KHz demand clock for RLINK.
24
RCLK
I
Receive Clock.
1.544 MHz primary clock.
25
RCHCLK
O
Receive Channel Clock.
192 KHz clock identifies time slot (channel) bound-
aries.
26
RSER
O
Receive Serial Data.
Received NRZ serial data, updated on rising edges of
RCLK.
27
RFSYNC
O
Receive Frame Sync.
Extracted 8 KHz clock, one RCLK wide, indicates F-
Bit position in each frame.
28
RMSYNC
O
Receive Multiframe Sync.
Extracted multiframe sync; edge indicates start
of multiframe, 50% duty cycle.
29
RABCD
O
Receive ABCD Signaling.
Extracted signaling data output, valid for each
channel time in signaling frames. In non-signaling frames, RABCD outputs
the LSB of each channel word.
30
RSIGFR
O
Receive Signaling Frame.
High during signaling frames, low during resync
and non-signaling frames.
31
RSIGSEL
O
Receive Signaling Select.
In 193E framing a .667 KHz clock which identi-
fies signaling frames A and C. A 1.33 KHz clock in 193S.
33
RST
I
Reset.
A high-low transition clears all internal registers and resets receive
side counters. A high-low-high transition will initiate a receive resync.
34
35
RPOS
RNEG
I
Receive Bipolar Data Inputs.
Samples on falling edge of RCLK. Tie togeth-
er to receive NRZ data and disable bipolar violation monitoring circuitry.
36
RCL
O
Receive Carrier Loss.
High if 32 consecutive 0’s appear at RPOS and
RNEG; goes low after next 1.
37
RBV
O
Receive Bipolar Violation.
High during accused bit time at RSER if bipolar
violation detected, low otherwise.
38
RFER
O
Receive Frame Error.
High during F-Bit time when F
T
or F
S
errors occur
(193S) or when FPS or CRC errors occur (193E). Low during resync.
39
RLOS
O
Receive Loss of Sync.
Indicates sync status; high when internal resync is
in progress, low otherwise.
